Product Specifications

Product Details

The pipe flange refers to the flange of the pipe distribution pipe in the pipe device, and the import and export flange of the equipment is used in the equipment. There are holes in the flange and bolts make the two flanges tightly connected. The flange is sealed with a gasket. Flanges are divided into threaded connection (thread connection) flanges, welded flanges and clamp flanges. Flanges are used in pairs, threaded connection flanges can be used for low pressure pipes, and welded flanges for more than four kilograms of pressure.
